What it is
Prebiotic inulin is a naturally occurring plant sugar, most often derived from chicory root. It’s part of a group of non-digestible carbohydrates called fructans, which serve as food for beneficial bacteria. In other words, a prebiotic.
While inulin is best known for its gut health benefits, it’s also making waves in topical skincare, where it supports the delicate balance of the skin’s microbiome. You’ll often find it listed on ingredient labels for face, hand or body products aimed at sensitive, dry or reactive skin.
How it works in skincare
Your skin is home to millions of microorganisms, known collectively as the skin microbiome. A healthy microbiome helps maintain your skin’s barrier function, supports immunity and keeps potential irritants or breakouts in check. Disruptions to this balance (from harsh cleansers, pollution or even over-washing) can leave your skin more vulnerable to dryness, inflammation and sensitivity.
That’s where prebiotic inulin comes in. When applied topically, it acts as a food source for the skin’s beneficial bacteria, helping them to thrive while keeping more aggressive strains at bay. Think of it as a gentle way to nudge your skin back into balance.
In hand and body care, prebiotic inulin can help reduce tightness, flaking and irritation by keeping the skin’s barrier more resilient- especially useful for skin that’s frequently washed or exposed to the elements. It pairs well with soothing moisturisers and hydrating cleansers and is especially kind to hands in need of barrier repair.
Prebiotic skincare doesn’t work overnight, but it can be an important part of restoring long-term skin comfort. You may find it especially helpful if your skin is easily upset, chronically dry, or prone to flare-ups.
